Barrel bushing

Recommended Posts

I have a nice little carriage clock in for service, very good shape, except for over 0.30mm sideshake of the barrel arbor in the barrel. Thought I would show how I bush these; it seems they often get overlooked or just skipped as they are a little more fussy than just bushing a plate. I measure everything up, then remove the boss in the barrel, and make a bushing that fits from the inside and is stepped, replacing the boss. This way it's captive, and doesn't require a big interference fit to get seated and stay. I turn up the bushing with a boring tool in the lathe, doing the outside as well (running in reverse of course), then do the barrel opening with the same tool. It's a pretty quick process once you have the moves down!

How did I miss this? I always let the bush protrude by a tiny amount on the face side, then clean off, that way by the time you have finished cleaning up and polishing the barrel you wouldn’t see the bush. Nevertheless a good tidy job. We all have our own ways of working.

    • Does anyone knows what size case a need for a dial diameter 20.60mm?
    • Sounds like the story with my Rolex. Poor (expensive) job done by an official Rolex dealer with an "in-house" watchmaker, hence I learned watchrepair and did the servicing myself. Same story as I learned with the Omega 861, again poor job by an "in-house" watchmaker by an official Omega dealer. Once your watch goes through that back-door, you have no idea what is going to happening to it 🫣 Quite nice that the sent back the parts which had been replaced !
    • yes that's definitely not right at all. I have a picture one of my friends has a Omega coaxial there was having issues to lose asking me where he should send it. As that's a specialty watch I suggested the service center. When he got it back he sent me a picture so the replace the dial as you can see the hands the mainspring barrel and I think the price was really quite decent considering all the stuff they can replace. So I do know they do change the barrels but the other person I worked at the service center when I would ask questions and unfortunately I can't remember all the answers. I think a lot of the changing a parts is at the discretion of the watchmaker. Plus I don't know enough about the chronographs and whether that would be considered a vintage watch? I take some of the vintage watches may have been sent directly to Switzerland or another service center. Obviously with a watch like the one down below they probably have a infinite supply of parts is its relatively modern vintage stuff becomes more interesting even the watch companies don't have necessarily infinite supply of parts. But no matter what the watch shouldn't disintegrated six months that's definitely an issue.        
    • glad it worked out, those ESA movements are obsolete but new old stock is still out there, now that you know the make/model you could also do a cross reference to see if something more current would line up with the dial feet and hands...for future use if needed 👍
    • I wish they would have done so in this case. The whole story went like this: I sent my speedmaster to an omega service center about 10 years ago (at that point of time I haven't even started watchmaking). After the watch came back to me it had only about 6 months wristtime until january 2024 (not fair for this nice watch but the other pieces of my collection want wristtime too 🙂). So my conclusion is that the barrel was already faulty when it came back from service, can't imagine that amount of wear in 6 months wristtime. In january 2024 the performance on the wrist was quite bad, so I decided to have a look by myself. I have to admit that I didn't check the barrel close enough as I thought it must be ok, couldn't have issues after official omega service. That was a mistake, I will learn from that. Follow the golden rule: Nothing is certain except death and taxes.
